Any number multiplied by 1 remains the same.One is called the Multiplicative Identity.Multiplying any number by one is an example of the Multiplicative Identity Property of One.The multiplicative identity states that:A x 1 = A
-9; the multiplicative inverse: -1/9
The property of multiplicative identity, i, of a set S is an element, is that for every element x in S,x * i = x = i * x
-5
it is 2/-1 or -2/1 it does not matter one is negative and it is 2 over 1
